My solution would be to just figure out how to make a high-quality renderer not take very long to render and leave it set for high quality.

Remember what life was like before MP3s?  You had 60,000 meg files for one song in a wav, and that wasn't very handy.

 

All of the sudden, MP3 codec, and BAM...off to the races.

Someone is going to "Mp3" the rendering business.
